4.Describe Von Neumann and Harward architecture.
5. Explain Bus structures ?
6. Explain the terms compiler, linker, assembler, loader and describe how a C program or any other high level language program is executed in a system. Indicate entire process with a figure
7. Explain about various buses such as internal, external, backplane, I/O, system, address , data, synchronous and asynchronous ?
8.List the steps needed to execute the machine instruction Add LOCA,R0 In terms of transfers between the components and some simple control commands. Assume that the instruction itself is stored in the memory at location INSTR and that this address is initially in register PC.

18. Distinguish between error detection and correction codes. What do you understand
by odd parity and even parity?. What is odd function and even function?. To calculate odd and even parity values which functions can be used? Calculate Odd and even parity values for all hexadecimal digits 0-9 and A-F
19. Explain with an example IEEE 754 single precision floating point representation
20. (a) What is meant by normalization in floating point representation?. Why do
need it? What is bias? What normalization is used in IEEE 754 standard?
(b) Explain about NaN and denormalised numbers in IEEE 754 standards.
